HBV deletion mutants complicate the progression of viral liver diseases.This study analyzed HBV sequences from 103 patients including 51 whole genomes and 70 preS clones.Among three hotspots we observed, including core, preS, and BCP regions, most deletions in core and BCP were out of frame, whereas almost all those in preS were in frame.The majority of deletions interrupted epitopes of viral proteins, suggesting possible mechanism for virus to evade immune surveillance.Furthermore, logistic regression analysis of whole genomes showed that among various clinical issues, only antiviral medication appeared to affect the accumulation of deletion mutants (OR =6.81, 95% Cl 1.296~35.817, P=0.023).

【摘 要】由于采用SNMP协议实现数据采集具有无须更改系统软件且无须停机的优势，所以这一协议目前在场面监视雷达自动化系统中应用日趋广泛。本文详细介绍了如何采用SNMP协议对场监自动化系统的相关参数进行数据采集，并与系统MIB库中的数据进行比对分析从而判断出系统是否处于正常运行状态的方法。通过具体实例，本文还给出了详细实现过程。 【关键词】SNMP协议；场监系统；数据采集；数据分析 0.引言
